A four-page installment from Posselt's Textile Journal (November 1912) on combining two systems of warp with one filling. It explains how to build double-faced satin fabrics and how to add an extra back warp for bulk in men's wear worsteds, with rules for placing face and back weaves on point paper. Figures 1-52 give draft examples for 1:1, 2:1 and mixed face-to-back arrangements using satins, twills, baskets and granite weaves. The last page continues the Lappet Weaving series, describing presser wheel and common wheel lappet ornaments (Figs. 6-9), including multi-frame work, open-work stripes and corded stripes.
